Arguments

x

a four dimensional image

center

a logical value indicating whether series should be centered

scale

a logical value indicating whether series should be divided by standard deviation

Examples

bvec <- NeuroVec(array(rnorm(24*24*24*24), c(24,24,24,24)), NeuroSpace(c(24,24,24,24), c(1,1,1)))
res <- scale_series(bvec, TRUE, TRUE)
